DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 5, a rectangular embodiment 10 of the invention is illustrated wherein a rectangular absorbent sheet member of terry-cloth or other absorbent fabric is divided into two equal portions 15 and 16 adapted to be folded over along a fold line shown by dotted line 17. Area 15 is provided with a fastening means 11 along its outer edges and area 16 is provided with fastening means 12 around its outer edges, so that fasteners 11 and 12 cooperate to engage and form an enclosure when areas 15 and 16 are folded over. Preferably 11 and 12 are of the hook and loop type of fastener known as Velcro, such as is described in US. Pat. Nos. 2,717,437; 3,l92,587; 3,387,341, etc. Other types of fasteners may also be used as long as satisfactory enclosure will result.

As shown in FIG. 3, element 20 is a pad or sheet of absorbent material, which may be a layer of cellulose or other sponge of suitable thickness, i.e. A to 1 inch thick, or else one or more layers of fibrous material such as felt, terry-cloth of the like capable of absorbing a substantial volume of liquid.

As shown in FIG. 4, element 18 is a flexible moisture retaining pouch slightly larger in dimension than ele ment 20 which it is adapted to receive. The pouch is preferably made of thin flexible plastic material such as polyethylene, polypropylene or else of thin vulcanized rubber, which materials are able to withstand the temperature of boiling water, or other heated fluids. The pouch is formed with an extension area or flap portion 19 adapted to be folded over to enclose the insert after it is placed therein.

The elements described in FIGS. 3, 4 and S are then assembled to produce the pack described in FIGS. 1 and 2 in the following manner, when the device is to be utilized as a hot pack. Absorbent member 20 is inserted into pouch 18. A measured quantity of hot water, sufficient to saturate the absorbent material is then poured into the pouch, flap 19 is folded over to prevent leakage after assembly, and the assembled unit is enclosed within 15 and 16 by folding them over and engaging the fastening strip members 11 and 12. The resulting structure is clearly illustrated in FIGS. 1 and 2. The hot pack is then ready for positioning upon a body member utilizing straps 13a, 13b and 13c of suitable length, the ends of said straps being provided with one portion of a Velcro" fastener member and corresponding areas 14a, 14b and on the opposite surface of 15 being provided with cooperating Velcro" members. Tabs 21 and 22 are provided as shown in FIGS. 1, 2 and S to permit easy removal of the pouch.

When intended to be used as a cold pack. the absorbent pad may be impregnated with ice water or other cold fluid, or may be replaced entirely with crushed ice. introduced into the pouch. When the pack is intended to be used over a large body area, such as chest or back, it may be positioned properly and held in place by elongated strap members 23 and 25 extending outward from the fold line area with the ends provided with cooperating fastening elements 24 and 26 respectively, also of the hook and loop type.

In a modified form of the invention shown in FlGS. 7-11 inclusive, :1 hot or cold pack especially suitable for application to the neck and upper cervical area of the spine is provided. As shown in FIG. 8, a rectangular fabric or sheet material elongated sufficiently to fit about the back of the desired wearer is provided having its four corners curved or contoured as shown at 28, 28a and 29, 29a. The sheet material is preferably porous of terrycloth, felt, or other fabric, but may be of thin sheet plastic material. The edges of member 27 are provided with cooperating fastening straps 44 and 44a of the Velcro type so that when it is folded along a central fold line shown by the dotted line in FIG. 8, an enclosure will result having the shape shown in FIG. 7. Within this enclosure may be positioned absorbent pad 30 within plastic pouch 31, rectangular in shape and elongated to conform to a substantial portion of the length of member 37 and to fit within the enclosure when its two halves are folded over. The outer surface of 27 is provided with a supplemental layer 32, also of elongated rectangular shape, which is provided on its inner edges with a strip of Velcro or the like fastening material 34, positioned to cooperate with corresponding fastening strap to define a pocket area 33.

When used as a hot pack, as shown in FlG. 9, the absorbent pack 30 within pouch 31 is saturated with hot water placed within 27 which is folded over thereby enclosing it within the contoured member shown in FIG. 7. In this case, layer 32 can remain as an additional insulating layer, or removed by detaching the fastening straps by a pull on tab 41. The assembly can then be placed around the neck of the wearer as shown in FIGv 6, with the contoured area 28 and 29 positioned beneath the chin of the wearer for comfort and fit. It can then be fastened by engaging cooperating Velcro" strap 37 or strap 36 with Velcro area 38 as shown in FIGS. 6 and 7.

When desired for use as a cold pack, as shown in FIG. 10, absorbent material 42 saturated with ice water, or replaced by crushed ice, is placed within pouch 43. This is then enclosed beneath member 32 over area 33 as shown in FIG. 8, within an enclosure formed by engagement of Velcro fastening straps 34 and 35. Upon folding member 27 and engaging straps 44 and 440, it can then be used as a cold pack with layer 32 in contact with the skin, while the double layer formed by 27 can serve as an insulating layer.

As shown in FIGS. 11l4, a cold and hot pack incorporating the features of this invention are adapted for application to an ankle to treat arthritis and injury causing swelling. As shown in FIG. 12, member 45 is shaped to fit around an ankle as shown in FIG. 11 and is provided with straps 52 and 53 having Velcro areas 54 and 55 at the ends adapted to engage cooperating fastening areas at the ends of straps 56 and 57. Member 45 is doubled to enclose a pouch 48 within which is positioned a heat or cold absorbent pad 49.

The pouch is retained within an enclosure formed by engaging fastening straps of the Velcro type. As shown the assembly has a generally hexagonal shape and when wrapped around an ankle has the appearance shown in FIG. 11. Detachably positioned over one surface of member 45 is a sheet member 58 having a similar configuration, orjust simply rectangular in shape attached by means of Velcro straps 60, 61, to provide an outer pocket 59 to receive a pouch containing either heating or cooling material similar to the form shown in FIG. 10. This permits use of the device around the ankle or other body member with only a single layer of fabric interposed. An additional strap member 62 is provided to pass under the ball of the foot and engage a cooper ating Velcro fastening area at 63.

in use the hot pack will provide moist heat when in contact with skin through perspiration and containment of the resulting moisture. Improved results are obtained either by moistening the fabric slightly before applying to the body, or by using a plastic pouch for receiving the hot or cold material formed of microporous film.
